thanks for this guide. TOPs javascript introduction was $hit, literally impossible to solve this without external help. there was literally almost no coding practice before this, only a bunch of useless text walls

Thank you so Much Giovanna, this is the most simplest breakdown I've seen from all the other solutions I was working with before

Thanks for this. Great guide to complete my 1st The Odin "Project".

Absolutely brilliant walkthrough

@6:50, my console keeps saying "Maths Not defined" And My code is exactly like yours; Function getComputerChoice() { Const choice = options [math.floor(math.random() * options.length)]; Console.log(choice); } getcomputerchoice () ; But my console keeps saying "Uncaught ReferenceError: math is not defined".

after trying to put prompt and doing rpm install prompt-sync I get the error : prompt is not defined what do I do?

Hi. When i play the game, it's throwing a logic error. If i chose rock and computer chose paper, it should console log that you lose! paper beats rock! But it is doing the opposite of that. why is that? My code is almost the same as yours. Here is it: const options = ["rock", "paper", "scissor"]; function getComputerChoice() { const choice = options[Math.floor(Math.random() * options.length)]; return choice; } function checkWinner(playerSelection, computerSelection) { if (playerSelection == computerSelection) { return "It's a tie"; } else if ( (playerSelection == "rock" && computerSelection == "scissor") || (playerSelection == "scissor" && computerSelection == "paper") || (playerSelection == "paper" && computerSelection == "rock") ) { return "Player"; } else { return "Computer"; } } function playRound(playerSelection, computerSelection) { const result = checkWinner(playerSelection, computerSelection); if (result == "It's a tie") { return "It's a tie!"; } else if (result == "Player") { return `You win! ${playerSelection} beats ${computerSelection}` } else { return `You lose! ${computerSelection} beats ${playerSelection}` } } function getPlayerChoice() { let validInput = false; while(validInput == false) { const choice = prompt("Rock Paper Scissor"); if (choice == null) { continue; } const choiceInLower = choice.toLowerCase(); if(choice.includes(choiceInLower)) { validInput = true; return choiceInLower; } } } function game() { let playerScore = 0; let computerScore = 0; for( let i = 0; i < 5; i++) { const playerSelection = getPlayerChoice(); const computerSelection = getComputerChoice(); console.log(playRound(computerSelection, playerSelection)); if (checkWinner(playerSelection, computerSelection) == "Player") { playerScore++; } else if (checkWinner(playerSelection, computerSelection) == "Computer") { computerScore++; } } console.log("Game over!") if (playerScore > computerScore) { console.log("Player was the winner!"); } else if (playerScore < computerScore) { console.log("Computer was the winner!"); } else { console.log("We have a tie!"); } } game() Thanks in advance to anyone who is willing to help 😁

Thank you!! I was struggling with announcing the score at the end and this helped me clean up my code to make it work. One thing I noticed: the score had a tendency to increment one point for the player on a tied round, resulting in an inaccurate end result. I added a line to prevent the code from incrementing for either player if the round was drawn. I really appreciate the time you took to make this video!

Thank you so much for this easy to follow along video! I was stuck on this assignment on TOP and I was easily able to follow and understand what you were doing. Thank you!

Hello, thanks for the video, but in the function getPlayerChoice, I do exactly the same as you did there, but the promp never shows, instead the game is played automatically 5 times, with all loses, any help with that?

Amazing and so simplified, thank you!!

Giovanna, eu estava com dúvida nesse código e após assistir o seu vídeo eu consegui finalizar o meu. Porém, ao inserir a função game e o loop, meu console mostra que o playerSelection não foi definido, mas se eu tiro a função, o jogo funciona, você poderia me ajudar?? const pick = ["rock", "paper", "scissors"] function getComputerChoice(){ const choice = pick[Math.floor(Math.random() * pick.length)]; return choice; } function checkWinner(){ if(playerSelection == computerSelection){ return "Tie"; }else if (playerSelection == "rock" && computerSelection == "scissors" || playerSelection == "paper" && computerSelection == "rock" || playerSelection == "scissors" && computerSelection == "paper"){ return "Player"; } else{ return "Computer"; } } function playRound(playerSelection, computerSelection){ const result = checkWinner(playerSelection, computerSelection); if (result == "Tie"){ return "It's a Tie!" } else if(result == "Player"){ return `You Win! ${playerSelection} beats ${computerSelection}` } else if (result == "Computer"){ return `You Lose! ${computerSelection} beats ${playerSelection}` } } function getPlayerChoice(){ let validatedInput = false; while(validatedInput == false){ const choice = prompt ("Rock Paper Scissors"); if(choice == null){ continue; } const choiceInLower = choice.toLowerCase(); if(pick.includes(choiceInLower)){ validatedInput = true; return choiceInLower; } } } function game(){ let scorePlayer = 0 let scoreComputer = 0 for(let i = 0; i < 5; i++){ const playerSelection = getPlayerChoice(); const computerSelection = getComputerChoice(); console.log(playRound(playerSelection, computerSelection)) console.log("-----") if (checkWinner(playerSelection, computerSelection) == "Player"){ scorePlayer++; } else if (checkWinner(playerSelection, computerSelection) == "Computer"){ scoreComputer++; } if(scorePlayer>scoreComputer){ console.log("Player wins!") } else if(scoreComputer>scorePlayer){ console.log("PC wins") } else { console.log("Tie again") } } } game()

she is the legend

This is an excellent walkthrough, thank you very much

OBRIGADA! i've been doing pretty well on the odin project but i would've never been able to do this by myself lol

Hi! I have to thank you for this guide. As somebody said here before me, as total beginner it was really frustrating to get this thing going from scratch without ever trying to write code in JS. html and css at the beginning was quite fast to learn, only flex box took me couple of days to get a grasp on. (gamify helped a lot - flexfrog! :) ) but I'd like to ask about one thing. PlayRound function is called how, in the for loop? by the console? It's the only thing that's bugging my head. I thought, that I have to call the function inside the for loop to make it run. Can you, or somebody please explain? thanks a lot!

Is there a part 2 for the revisiting rock paper scissors?

18:09 I'm a little confused here. Aren't you supposed to first put 'else'? or is that optional?

Anyone has the same video but the revisiting one, please?

Thank you very much

thank you for video.I've got question can you sing?

It all works fine except that the prompt doesn't allow anything to show in the console. I have to comment out the function then open the page with live server , then go Back and uncomment the function. Is there a way around this? I tried settimeout but it didn't work either

hello! awesome video. But how do i push to my github. Im having a difficult time doing so. Thank you

Thanks. God bless!!!

what is the app she uses at the end to push all her work?

Perfect, thank you! exactly what I needed

The way she says winner tho 😂

I have a problem where the game function is asking for twice as much input and only the second input is taken in as input. function game() { for ( let i = 0; i < 5; i++) { const playerSelection = getPlayerChoice(); const computerSelection = getComputerChoice(); console.log(playRound(playerSelection, computerSelection)); } } Same as yours. I tried commenting out the const`s and resulted in error, once i commented out the console.log it just asked 5 times for input. The problem is visible but why is the code running like this?

I wrote the code exactly as you did in the video for getPlayerChoice function, but when the page loads the prompt and you enter a choice, the console doesn't log anything and it just restarts the loop? Am I writing something wrong here? function getPlayerChoice(){ let validatedInput = false; while(validatedInput == false){ const choice = prompt("Rock Paper Scissors"); if (choice == null){ continue; } const choiceLowerCase = choice.toLowerCase(); if (options.includes(choiceLowerCase)){ validatedInput = true; return choiceLowerCase; } } }
